Monitoring engine not working

[wiproltdwiv]

Hi Team,

When we do applying configuration post that monitoring engine goes stop, also external commands also goes auto stop. Cause of checks not happen and Nagios look like as stand by. Currently we are monitoring approx 1300 hosts and 6000 services.

please find the error screenshot as well Nagios system profile.

Can you post your nagios.cfg

Also, at what frequency are you monitoring the 1300 hosts and 6000 services?

What are the specs on your server CPU's, RAM

[wiproltdwiv]

we have assign 10 to 15 check interval for all hosts and services. i have attached nagios.cfg also below are the hardware details.

winproltdwiv,

Are you able to roll back to a working snapshot?

Core Config Manager->Configuration Snapshots


Thanks,

[wiproltdwiv]

I can, but i am not getting any error snapshot all are getting successfully only.

It seems like your system could be overtaxed, either with Disk IO, or CPU load. The following document might be worth a read.

[wiproltdwiv]

I went through above doc, but as per our system h/w configuration and attached system status, i dont think we have that much load. Please check and suggest where we need to changes

Have you tried rolling back to a previous snapshot? Regardless if they are stamped with error or are clean.
